Suppose that $(X,d)$ be a complete metric space, $f:X \to \mathbb{R}$ is a sequentially lower monotone function. Let $g: X \to \mathbb{R}$ be a function with the property: $f(x)\leq f(y) \Rightarrow g(x)\leq g(y), \forall x,y \in X.$
Can we say $g$ is also sequentially lower monotone?

**Remark:** A function $h:X \to \mathbb{R}$ is said to be sequentially lower monotone on a point $x_0 \in X$, if for all sequence $\{ x_n \}_{n \in \mathbb{N}}$ with $h(x_{n+1})\leq h(x_n)$ (for large n's), which converge to $x_0$, we have $h(x_0)\leq\liminf_{n \to \infty}h(x_n)$. A function is said to be sequentially lower monotone, if it is sequentially lower monotone in each $x \in X$. It is an extension of lower semi-continuity. The answer of the question is negative for lower semi-continuous functions.
